Use a square sheet of paper
Fold the paper in half horizontally
Unfold it
Fold the top edge to the center crease
Fold the bottom edge to the center crease
Fold the paper in half along the center crease
Cut the folded strip into two equal rectangles
Take one rectangle and fold it in half lengthwise
Fold one corner down to make a triangle flap
Fold the strip again in the opposite direction to create a zigzag shape
Repeat the folding pattern until the strip is fully folded
Make a second folded strip the same way with the other rectangle
Place one strip over the other in a cross shape
Tuck the ends of each strip into the pockets of the other strip
Tighten the folds to form the ninja star shape
Adjust the points so they are even and secure
